Flat roof replacement across Costessey
Dense streets in Costessey mean shared valleys, party walls and restricted scaffold positions. If you are looking at flat roofing & epdm in Costessey, the practical questions are usually the same: what is actually failing, how much of the roof it affects, and whether it can be repaired or needs replacing. We answer those on site, free of charge. Longwater anchors this part of Costessey, and the properties around it are the ones we are called to most.

Why Norfolk roofs fail
Our home patch — estates, bungalows and extensions.
Access near Longwater
Scaffold, unloading and parking around Longwater are agreed before the van arrives, so nothing on your side of the road is blocked longer than it needs to be.
Properties around Costessey Park
The buildings closest to Costessey Park take the brunt of the weather from that side, and they are the ones we are asked to look at most often here. The same applies along the approach to the River Tud meadows.
Split and blistered felt
Old bitumen felt splits at movement joints and blisters where trapped moisture expands. Overlaying rarely fixes either.
Ponding water
Flats laid without enough fall hold water for days, which shortens the life of any membrane. Falls and outlet positions get reset, not covered over.
Materials and systems we use
- Warm-deck insulation build-ups
- Insulation above the deck keeps the structure warm and reduces condensation risk compared with old cold-deck details.
- EPDM rubber membrane
- One-piece rubber for extensions, dormers and garages — no field seams, and it copes well with movement.
- GRP fibreglass
- Laid in situ over a ply deck for balconies and anything walked on, finished with a hard topcoat.
- Trims, upstands and outlets
- Edge trims, correctly formed upstands and adequate outlets — where nearly all flat roof failures actually begin.

Questions we get asked in Costessey
- How long should a new flat roof last?
- A well-installed EPDM or GRP roof on a sound, correctly falling deck should give decades of service. What kills flat roofs early is ponding water, poor upstands and being laid over a wet deck — all avoidable.
- Can you overlay the existing felt?
- Only if the deck below is dry and sound, and we'll lift a section to check. Overlaying a soft deck buys a year or two and costs the whole job again.
- Why does water sit on our flat roof after rain?
- Insufficient fall, a sagging deck or a blocked outlet. On Costessey extensions it's usually falls that were never set properly. We reset falls with firrings rather than lay new membrane over the same puddle.
- EPDM, fibreglass or felt — which should we choose?
- It depends on the deck, the traffic it takes and the budget. EPDM suits most extensions and garages, GRP suits balconies and anything walked on, and felt still makes sense on larger or awkward outbuildings. We'll set out the options at inspection.
- What does a flat roofing & epdm quote in Costessey cost?
- The inspection and the written quotation are free. The job price depends on the covering, the roof size, access and what we find under it — which is exactly why we won't price it over the phone.
